arcpy.mapping.ListLayers

Question

Hey all,

I have 20 features classes, each with multiple fields, but ALL containing a field titled "AFE_Number."  I need to create a script to loop through a list of All feature classes and select any/all with the "AFE_Number" field containing a specific #.   I am able to generate a list of the necessary features, but am unable to selectbyattribute for more than one at a time.  Any suggestions?  Thanks a bunch

Try this:
param1 = arcpy.getParameterAsText(0)
lyrList = param1.split(';')

The multivalue paramater will return you the values seperated by semi-colon if you use the split method on a string it will return you a list of items delimited by the character you pass into the method.

Is there a way to populate a list file via an arcpy.GetParameterAsText()  ?    Set a list [] variable equal to the value/s of a GetParametAsText.  Seems like you could add the script in ArcMap and set the parameters as a multivalue and select all feature classes, then loop through them.   Any ideas if something like this could work?

I believe you are right about creating a list of fc's [a,b,c,...] and looping.  Seems to be my only option.  I appreciate your input.  Im still new to the Python game and needed some advice.  Thanks
